LSD celicasupra rear should have the last number odd like a F283 and so on ive got an 79rear on mine F312 which translate to 3.9 gear ratio non LSD but good find though they are getting pricey these days 500bucks or so for a complete rear end

From what I've heard you can also use an LSD from a 84-85 Celica GTS too

only if you have the 7.5" f code carrier. if you have a 6.7" t code it wont fit also the 84 wasn't lsd equipped only the 85 was. if anybody is looking for a 7.5" f code non lsd rear there is a complete 80 supra nearby me that runs and drives for 500 bucks. my finders fee is the trans and pedal assembly though and you can have the rest of the car

ONLY the '85 Celica GT-S (IRS) with a manual trans came with a 7.5" (F-code) diff - F312. I've never heard of one with LSD in the US - maybe from Canada. Your best bet for an LSD carrier is out of a Mk II Supra or a truck.All other RWD Celicas - '71-'85 - (NOT Supras) came with 6.7" (T-code) diffs, and none of those had LSD.All Mk I and Mk II Supras came with F-code diffs, but only Mk I's from Canada had LSD. Many Mk II's had LSD.Mk I's are SRA, Mk II's are IRS. All have 4-wheel disc.

Well YOUR diff isn't LSD because it's still sitting on the ground somewhere! lol snicker snicker
